Your new dbt project "{project_name}" was created! If this is your first time
|
|
using dbt, you'll need to set up your profiles.yml file -- this file will tell dbt how
|
|
to connect to your database. You can find this file by running:
|
|
|
|
{open_cmd} {profiles_path}
|
|
|
|
For more information on how to configure the profiles.yml file,
|

please consult the dbt documentation here:
